(cellulose soluble)
Water-soluble cellulose derivatives account for 38% of the global hydrocolloids market (Grand View Research, 2023), with applications spanning pharmaceuticals to construction materials. These modified cellulose compounds dissolve completely in aqueous environments while maintaining the polymer's inherent biodegradability.
Third-generation methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC) demonstrate:
Cross-linked carboxymethyl cellulose (CMC) shows 99.8% solubility within 30 minutes under controlled hydration conditions.
Manufacturer | Solubility Rate | Viscosity (mPa·s) | Purity (%) | Price (USD/kg) |
---|---|---|---|---|
Ashland | 98.7% | 15,000 | 99.5 | 28.50 |
Dow Chemical | 99.1% | 22,000 | 99.8 | 34.20 |
Shin-Etsu | 99.5% | 18,500 | 99.9 | 31.75 |
Customizable parameters for industrial buyers include:
Pharmaceutical-grade HPMC meets USP-NF specifications with ≤0.1% residual solvents.
A European construction materials producer achieved:
"42% reduction in mortar drying time using optimized HPMC blends (DS 1.8-2.2) while maintaining 98% water retention capacity."
Third-party testing parameters include:
Emerging cellulose solubility enhancement methods show 35-40% energy reduction in production processes (Cellulose Chem. Technol., 2024). Enzyme-assisted modification techniques enable precise control of substitution patterns while maintaining 99.9% aqueous solubility.
(cellulose soluble)
A: No, cellulose is generally insoluble in water due to its strong hydrogen bonding and crystalline structure. Its β-1,4-glycosidic linkages create a rigid polymer that resists interaction with water molecules.
A: Cellulose’s insolubility arises from its extensive intramolecular and intermolecular hydrogen bonds. These bonds form a tightly packed structure that water cannot easily penetrate or dissolve.
A: Yes, chemically modified cellulose derivatives like carboxymethyl cellulose (CMC) or hydroxypropyl cellulose (HPC) are water-soluble. These modifications disrupt hydrogen bonding, enhancing solubility.
A: Cellulose dissolves in specific solvents like ionic liquids, concentrated acids (e.g., sulfuric acid), or alkali solutions (e.g., NaOH/urea mixtures). These break hydrogen bonds or chemically alter the polymer.
A: Water-soluble cellulose derivatives are used in food additives, pharmaceuticals (tablet coatings), and industrial products (thickeners). Their biodegradability and non-toxicity make them widely applicable.
